RAZOR.

Application filed June 13, 1923. Serial No. 645,054

appliances, and pertains more particularly to razors of the single,sharp-edge type.

One object of the invention is the provision of a razor having a bladewhich may be especially easily removed therefrom and replaced therein.

A further purpos of the invention resides in supplying adjustment meansfor the blade to secure the desired cutting or shaving action, suchadjustment being toward and from the toothed guard usually employed onsuch razors adjacent to the sharp edge of the blade.

In order that those skilled in this art may have a full and completeunderstanding of the invention and its several structural and functionaladvantages, in the ac companying drawing forming a part of thisspecification, I have illustrated a desirable and preferred embodimentof the invention, and throughout the several views of such drawing likereference characters have been applied to the same parts.

In this drawing,

Fig. 1 is a face view of the novel and improved razor;

Fig. 2 is a side view of the same;

Fig. 3- is an enlarged, central, vertical or-longitudinal sectionthrough the razor;

Fig.4'is 'a fragmentary, lengthwise, central section at right angles tothat of Fig. 3 Fig. 5 is a section on the inclined plane 5-5 of Fig. 3;j I

Fig. 6 is a similar section, on a smaller scale, showing the blade inplace;

Fig. 7 is a view similar to that of Fig. 6, illustrating the blade witha different adjustment; Y 1

Fig. 8 is a detail view of the blade ad justing mechanism; 7

Fig. 9 is a perspective view of the cam employed for adjusting theblade;

Fig. 10 is a'perspective view of the clamp or face-plate for holding theblade in the razor; and v Fig. '11 is a face-view of the blade.Referring to'these several views ofthe draw g. t w ll he P---ld that themai round body of the razor comprises a hole low orlongitudinally-apertured member 21."

having a round hole 22 through the upper portion thereof whlchcommunicates with a larger, cylindrical cavity or bearing iu' the lowerportion of such element, the top annular face 24 of the member 21 beingsomewhat inclined or at an oblique angle to'the longitudinal axis of'thebody, as is clearly indicated in 3.

Extending outwardly from the face 24;, the part 21 is equipped with acylindrical,

shouldered, apertured boss 25 and an ineclined or slightly obliquemember 26 having along one edge the usual or customary spaced guardteeth 27 of slightly less thick ness than the part-26, is securely andrigid- 1y fastened on the outer or upper portion of the stud 25 bearingat its inner face on the slight shoulder of the stud, the outer portionof which is headed over slightly in the countersunk central hole of thepart 26 to center and affix the latter rigidly in position.

Along the central portion of the rear or back edge of this inclined oroblique blade-support 26, it is fitted with anup standing marginalflange or rib 28, and projecting downwardly from its opposite ends thereare a pair of cross or transverse,

marginal, spaced flanges or ribs 29, 129,

shown most clearly in the section of Fig. i.

A plate 31 is positioned beneath the bladesupport 26, between its twoflanges 29, 29, which act as retaining guides therefor during thelateral adjustment movement of the part 31, the latter having two,upstanding lugs or ears 32, 32, eXtending up through cut-away cornerportions 33, 33, of the member 26, as is perhaps most apparent from theillustration presentedin Fig. 5. A round, apertured disk 34, hearing onthe surface 24 and carrying adepending, manipulating or adjusting fingeror lug 35, is mounted on and revoluble or capable of turning on thelower or inner part of the hollow stud 25, and such disk is equipped onits top or upper face with a curved or arouate cam 36 received in anelongated opening or aperture 37 in .theblad-eadjustment plate (Figs. 8and 9), whereby turning or rocking of the member 3t'by its handle 35shifts or adjusts the lugs 32,32, toward and from the toothed edge 27 ofthe guard.

Owing to the sli htl y elongated shape of the hole dispose with itslonger faggig lengthwise the part 31, this plate 31 has no endwisemovement occasioned by the turn ing of the cam, but it is guided in itscrosswise or lateral motion by the flanges or marginal ribs 29, 29, withwhich its ends coact.

A face plate 38, having a plane upper surface 39 and an outer,slightly-curved or convex face 41,.is supplied-with a threaded stem orshank 42 designed to be removably received in the aperture 22 whichextends through the stud referred to, and to project into the threadedinn-er end 43 of a hollow, tubular member 44 fitting and revoluble inthe bearing or cavity 23, and supplied with an exposed, enlarged,preferably knurled or ribbed head or terminal part 4 5, by which it maybe turned to draw the clamp plate 38 down firmly against the blade tohold the latter fixedly in position.

The member 38' has a downwardly-extended flange 46 which lies to therear of the flange or rib 28 and the lugs 32, 32, whereby turning orrotation of the clamjnng-plate is prevented when it is being tightenedby the.

The ends of the blade are desirably round ed or slightly convex, asshownin Fig. 11, to

avoid unnecessary sharpcorners or edges, and the longitudinal cuttingedge 49 is formed at the junction of the bottomplane face of the bladeand a bevel surface 51 at a substantial. angle thereto, for instance, insome cases this may be approximately thirty degrees, which hasheretofore been considered altogether too blunt an edge for shavingpurposes.

To insert; the blade in the razor, the handle 45 is given a slight turn,and thereupon the blade is pushed entirely into place, the slot 48receiving the stem 42, and the rear edge of the blade bearing againstthe front faces. of the two shoulders 32. Then the handle is given asmall turn to draw theelamp-plate 358 down into gripping and holdingaction on the blade, the latter nowbeing held firmly and fixedly in.position.

It will be observed: that-to insert a blade, orto remove one by areversal of the operation specified, it'is not necessary to separate anyparts of the razor, a mere loosening of them being sutlioient for thepurpose.

If adjustment of the blade crosswise is desired to modify its cuttingaction by shifting the blade-edge with "relation'to the toothed guard27, the handle 4+5 is turned sli htly to free the pressure on, theblade, and then the cam 36 is manipulated by a turning of the handle 35tomove the lugs 32 forwardly or rearwardly the desired amount, the bladebeing correspondingly shifted, whereupon the handle 45 is again turnedto clamp the blade down immovably in place.

It will be seen that the adjustment of the blade is easily and readilyaccomplished, and when it is desired to remove the blade, the handle 45is turned only very slightly, whereupon the blade can be taken outforwardly by grasping its opposite rounded ends between the thumb andfinger.

So far as, I know, I am the first person who has provided an adjustmentof this kind, whereby the blade may be moved crosswise or laterally tobring it into proper position, and I also believe that I am: the firstone to supply a razor of this type wherein the blade may be removed oranother one inserted byaw'ery small-turning of the handle and withoutcomplete release of any other element.

It will be noted that the handle or lug 35 is up under the head of'the'razor, so that it is not conspicious, and is not at all in the way, andyet it is in a convenient position for ready manipulation when requircd.

In this application 'I have presented only one embodiment of theinvention, but the atter is susceptible of a variety of embodi mentsdiffering from one another more or less radically in mechanicalfeatures, but all incorporating the-fundamental principles underlyingthe invention.

The razor-blade disclosed in this patent forms the subjectsmatter of adivisional pending patent application, Serial Number 725,816, filed July14-, 1924-.
